CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation application of application Ser. No. 11/992,088 filed Mar. 14, 2008, which is a United States national phase application under 35 USC 371 of International application PCT/JP2006/318674 filed Sep. 14, 2006. The entire contents of each of application Ser. No. 11/992,088 and International application PCT/JP2006/318674 are hereby incorporated by reference herein.

TECHNICAL FIELD

The present invention relates to a novel 1-2-dihydroquinoline derivative or a salt thereof, which is useful as a pharmaceutical. The derivative has a glucocorticoid receptor binding activity and is useful as a glucocorticoid receptor modulator having a nonsteroidal structure (a glucocorticoid receptor agonist and/or a glucocorticoid receptor antagonist).

BACKGROUND ART

A glucocorticoid receptor is a 94 kDa ligand-activated intracellular transcriptional factor that is a member of the nuclear receptor superfamily. This receptor is known to regulate the metabolism of carbohydrates, proteins, fats and the like, suppress the immune or inflammatory responses, activate the central nervous system, regulate cardiovascular function, and affect basal and stress-related homeostasis and the like due to its transcriptional regulatory, action. As glucocorticoid receptor-related diseases, metabolic disorders such as diabetes and obesity, inflammatory diseases such as enteritis and chronic obstructive pulmonary diseases, autoimmune diseases such as connective tissue diseases, allergic diseases such as asthma, atopic dermatitis and allergic rhinitis, central nervous system diseases such as psychiatric disorders, Alzheimer's disease and drug use disorders, cardiovascular diseases such as hypertension, hypercalcemia, hyperinsulinemia and hyperlipidemia, homeostasis-related diseases causing an abnormality of neuro-immune-endocrine balance, glaucoma and the like are known (SOUGOU RINSYOU, 54(7), 1951-2076 (2005) and JP-A-2002-193955).

Therefore, a compound having a glucocorticoid receptor binding activity is considered to be useful as a preventive and/or therapeutic agent for these diseases.

As such a compound having a glucocorticoid receptor binding activity, glucocorticoid receptor agonists synthesized in the living body such as cortisol and corticosterone, synthetic glucocorticoid receptor agonists such as dexamethasone, prednisone and prednisilone, non-selective glucocorticoid receptor antagonists such as RU486 and the like are known (JP-A-2002-193955).

On the other hand, compounds having a 1,2-dihydroquinoline structure are disclosed as steroid receptor modulators in WO 2004/018429, JP-T-10-0510840 and the like. The compounds disclosed in WO 2004/018429 and JP-T-10-0510840 have a 1,2-dihydroquinoline structure, however, a compound in which any of various substituents has been introduced at the 5-position of the 1,2-dihydroquinoline structure has not been specifically disclosed therein.

DISCLOSURE OF THE INVENTION

Under argon atmosphere, lithium aluminum hydride (1.48 g, 39.0 mmol) was suspended in anhydrous tetrahydrofuran (30 mL). A solution of 2,2,4-Trimethyl-1,2-dihydro-6-oxa-1-azachrysen-5-one (Reference Compound No. 1-1, 3.80 g, 13.0 mmol) in anhydrous tetrahydrofuran (40 mL) was added dropwise at 0° C. and the reaction mixture was stirred at the same temperature for 1 hour. Ethyl acetate (15 mL) and water (5 mL) were added dropwise successively to the reaction mixture and then 0.2 N aqueous HCl solution (350 mL) was added thereto. The whole was extracted with ethyl acetate (300 mL, 100 mL). The combined organic layer was washed with water (300 mL) and saturated brine (100 mL) successively, dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure to give the titled reference compound (4.01 g) as a pale brown solid. (Yield quantitative)

After cooling down, the reaction mixture was diluted with ethyl acetate (200 mL) and diethylether (300 mL). The whole was washed with water (500 mL, 300 mL) and saturated brine (200 mL) successively, dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled Reference Compound No. 4-1 (3.01 g, Yield 71%) and the titled reference compound No. 4-2 (380 mg, Yield 9%) as a pale yellow solid respectively.

After cooling down, it was diluted with ethyl acetate (25 mL). The whole was washed with water (30 mL, twice) and saturated brine (30 mL) successively, dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (23 mg) as a pale yellow oil. (Yield 41%)

After the saturated aqueous NH₄Cl solution (5 mL) was added to the reaction mixture, the reaction mixture was diluted with ethyl acetate (100 mL). The whole was washed with water (100 mL) and saturated brine (50 mL) successively, dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (80.2 mg) as a pale yellow solid. (Yield 82%)

5-(5-Fluoro-2-methylphenoxymethyl)-6-(4-hydroxy-2-methoxyphenyl)-2,2,4-tri methyl-1,2-dihydroquinoline (Reference Compound No. 5-3, 20.1 mg, 0.046 mmol), potassium carbonate (16.7 mg, 0.12 mmol) and benzyl bromide (6.6 μL, 0.055 mmol) were dissolved in anhydrous N,N-dimethylformamide (0.5 mL), and the mixture was stirred at 60° C. for 40 minutes. Ethyl acetate (50 mL) was added to the reaction mixture, and the whole was washed with water (50 mL) and saturated brine (30 mL), dried over anhydrous magnesium sulfate, and then the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to give the titled compound (5.1 mg) as a colorless oil. (Yield 19%)

[Pharmacological Test] 1. Evaluation Test for Binding Activity to Glucocorticoid Receptor (Hereinafter Referred to as “GR”)

In order to evaluate a binding activity to GR, a receptor competitor assay was carried out by a fluorescence polarization method. In the assay, a GR competitor assay kit (manufactured by Invitrogen, cat No. P2816) was used, and a procedure was carried out according to the protocol attached to the kit. Hereinafter, the specific method will be described.

(Preparation of Reagents)

GR screening buffer: A buffer containing 10 mM potassium phosphate (pH 7.4), 20 mM sodium molybdate (Na₂MoO₄), 0.1 mM ethylene diamine tetraacetic acid (EDTA), 5 mM dithiothreitol (DTT), 0.1 mM stabilizing peptide and 2% dimethylsulfoxide was prepared.

4×GS1 solution: Fluormone™ GS1, which is a fluorescent glucocorticoid ligand, was diluted with GR screening buffer, whereby a 4 nM solution was prepared.

4×GR solution: Recombinant human GR was diluted with GR screening buffer, whereby a 16 nM solution was prepared.

(Preparation of Test Compound Solution)

After a test compound was dissolved in dimethylsulfoxide, the resulting solution was diluted with GR screening buffer, whereby a 20 μM test compound solution was prepared.

(Test Method and Measurement Method)

1) The test compound solution was added in an amount of 25 μL or 10 μL into each well of a 96-well or 384-well plate, and then, 4×GS1 solution and 4×GR solution were added in an amount of 12.5 μL or 5 μL into each well, respectively.

2) The plate was incubated in a dark place at room temperature for 2 to 4 hours.

3) By using a multimode plate reader, Analyst™ HT (manufactured by LJL Biosystems), fluorescence polarization of each well was measured. As the blank, a well containing GR screening buffer in place of the test compound and 4×GS1 solution was used.

4) The same procedure as that in the above 1) to 3) was carried out except that GR screening buffer was used in place of the test compound solution, and the obtained result was taken as the negative control.

5) The same procedure as that in the above 1) to 3) was carried out except that 2 mM dexamethasone was used in place of the test compound solution, and the obtained result was taken as the positive control.

(Calculation Equation of GR Binding Ratio)

A GR binding ratio (%) was calculated from the following equation.

GR binding ratio(%)=100×[1−(fluorescence polarization of test compound solution−fluorescence polarization of positive control solution)/(fluorescence polarization of negative control solution−fluorescence polarization of positive control solution)]
